Security

The Security screen manages your personal account security: two-factor authentication (2FA) with an authenticator app, backup codes, and the list of active sessions (devices where you are logged in), each of which can be revoked.

Accessing Security​

In the sidebar, open My Account → Security (/settings/security).

Personal, not per-site

Everything on this screen belongs to your user, not to a site or organization. Changing your password is done on the My Account → Profile screen, not here.

Security Status​

The top card summarizes your account: it shows how many devices are currently logged in. When there is more than one session, a Logout All Other Sessions button appears — see Active Sessions below.

Two-Factor Authentication​

2FA adds a second verification step at login using a TOTP authenticator app (Google Authenticator, 1Password, Authy, etc.).

Enabling 2FA​

If 2FA is not enabled, the card shows 2FA Not Enabled with an Enable 2FA button. Setup is a guided four-step dialog:

  1. Password — enter your account password to begin.
  2. Scan QR code — scan the QR code with your authenticator app. If you can't scan, copy the secret shown below the code and enter it manually. This step also displays your backup codes — save them before continuing (there is a Copy All Codes button). Click I've saved my backup codes to proceed.
  3. Verify — enter the 6-digit code from your authenticator app and click Verify & Enable.
  4. Success — 2FA is now active on your account.

Cancelling the dialog before verification aborts the setup — nothing is enabled until the code is verified.

Once enabled, the next login asks for a 6-digit code (or a backup code) after your password.

Backup codes​

Backup codes let you log in if you lose your authenticator device. 10 codes are generated at setup; each one is single-use. The card shows how many remain ("X of 10 codes remaining").

To generate a fresh set, click Regenerate Codes, enter a 6-digit code from your authenticator app, and click Generate New Codes. The new codes are displayed once with a Copy All Codes button.

Old codes stop working

Regenerating backup codes invalidates all previous codes immediately.

Disabling 2FA​

Click Disable 2FA. The confirmation dialog requires both:

  • Your account password
  • A verification code — either a 6-digit code from your authenticator app or a backup code

After disabling, only your password is required to log in.

Active Sessions​

The Active Sessions card lists every device with a valid login session. For each session it shows:

  • Device and browser — operating system (Windows, macOS, Linux, Android, iOS) and browser (Chrome, Firefox, Safari, Edge), derived from the user agent
  • Last active — relative time of last use ("5 minutes ago", "2 days ago")
  • IP address — where the session was created, when available

Your current session is highlighted with a Current session badge and cannot be terminated from the list.

Revoking a single session​

Each other session has a trash icon. Clicking it terminates that session immediately — the device is logged out and must authenticate again.

Logout all other sessions​

The Logout All Other Sessions button (in the Security Status card) opens a confirmation dialog. Confirming will:

  • Log out every session except the current one
  • Invalidate all existing tokens on those devices
  • Require re-authentication on those devices

Use this if you suspect a session you don't recognize — and consider changing your password on the Profile screen as well.
